application from my PC, so there is no other servers/containers between (like tomcat etc).

Any ideas to fix my timeout settings?

Using a

Apache CXF 3.0.1

EDIT

What I realized now that I'm getting 2 diffrent messages depends on my timeout settings:

If I set it to

<=4min

(via my or @pedrofb method), after that amount of time I'm getting:

org.apache.cxf.interceptor.Fault: Could not send Message.
